Hello Kevin,
If you need a constant current source then an LED driver is a good option, that is what they are set up for. The LM3405A should work well for you.
As for other optimizations that kind of depends. But it's a relatively simple circuit so…
Part Number: LM3405A
Hello everyone,
I am looking to drive a display back light. According to the vendor of the display,it is constant current driven. The voltage is typical 9.9V. The typical current is 200mA. Input Voltage is 12V. I wanted to know…
Part Number: LM3405A Other Parts Discussed in Thread: TINA-TI , LM3405 , LM3406 Tool/software: TINA-TI or Spice Models Hi,
How is it possible to do a simulation running the LM3405 when there is no model for it?
Part Number: LM3405A Other Parts Discussed in Thread: LM3405 , LM3406 , TPS92515 , TPS92511 I am working on an LED retrofit to be used with an AC-dimming Halogen lamp supply. (10,000 units in the field!)
This will be running a single white LED at about…
Part Number: LM3405A Other Parts Discussed in Thread: LM3405 , , TPS92515 , TPS92518 , LM3409 Hello,
we use in our application 2 LM3405 devices.
Each of the LM3405A drives a Group of 4 LED´s in series.
Both of the LM3405A get the same PWM-Signal…
Other Parts Discussed in Thread: LM3405A Hi,
I have some trouble getting the LM3405A to work properly - I'm using the circuit and recommended parts from page 18 on the data sheet. Vin=5V driving a single LED @ 1A I do not get 1A current instead I get…
Other Parts Discussed in Thread: LM3405A , LM3405 , TPS92513 Hello
My name is Charlie.
I have 2 questions about LM3405A.
1. I use two LM3405A to drive 2 strings ×3LEDs （total 6 LEDs）. In order to prevent the interference of swtiching frequency …
Other Parts Discussed in Thread: LM3405A Hi Team,
Is there spice model for LM3405A? My customer would like to run SPICE simulation.
Best Regards, Yaita / Japan disty
Other Parts Discussed in Thread: LM3405A Hello,
I have the question of LM3405A about RZI calculation. Please see the attached file. LM3405A_RZI.pdf
I simulated the LM3405A with some Vin value( Vin=9V, Vin=18V, Vin=9V~18V) As a result the Rzi values…
Other Parts Discussed in Thread: LM3405A , CSD17313Q2 Hi,
I am working on an LED driving scheme using LM3405a and CSD17313Q2. We have multiple RGBW LEDs on our board. We are using MSP430 controller to control the PWMs through the mosfets, this is done…
